Abstract of Talk:
Nowadays microprocessor development has moved into a new era of many-core on-chip design, with tens or even hundreds of cores fitting within a single processor chip to speed up computing. However, conventional electrical interconnect for inter-core communication is limited by both bandwidth and power density, which creates a performance bottleneck for microchips in modern computer systems - from smartphones to supercomputers, and to large-scale data centers. Optical Network-on-Chip (ONoC), a silicon-based optical interconnection among cores at the chip level, overcomes the limitations of conventional electrical interconnects by supporting greater bandwidth with less energy consumption, and opens the door to bandwidth- and power-hungry applications such as big data analysis and general artificial intelligence. However, existing ONoC designs do not fully take the advantages of optical communication to maximize performance and save energy at the networking level. This talk will introduce challenging research problems on ONoCs from a networking perspective and present our current results for designing efficient routing schemes specific for ONoCs. Brief introduction about University of Otago and other research topics in system research group (open for Ph.D scholarship applications) will also be introduced.
Yawen Chen obtained her PhD degree in Computer Science from The University of Adelaide in Australia in 2008. After her Phd study, she worked as postdoctoral researcher at Royal Institute of Technology (KTH) in Sweden and Otago University in New Zeland during 2009-2011. She was appointed as Lecturer in Department of Computer Science at Otago University from 2012 and promoted to Senior Lecturer from 2018. She received Marsden Fund awarded by Royal Society of New Zealand (Principal Investigator, successful rate ~7%) in 2016. Her research interests include network-on-chips, optical networks, wireless optical networks, multicore computers, wired/wireless networks.
